FILLING FEELER KNIFE TRIPPERe Filed sept. 14, 192g 2 sneaks-sheet 2 Inventar 'daind M ttorng' Patented Apr. 14, 1931 AUNITED STATES THOMAS A. ADAMS, on BRENHAM, TEXAS 'FILLING-IEEELER-IKNIEE TRIPPER Application filed September 14, 1928. Serial No. 305,961.

4The present invention relates to improvements in attachments yfor filling replenish-,I

ing looms and has reference moreparticularly to a filling thread cutter tripping mechanism. 5 One of the important objects of the present invention is to provide a fillingfeeler knife tripper that includes a horizontally disposed arm for attachment at its inner end on the end of the breast beam associated with the hopper stand, said arm extending forwardly for disposition adjacent the shuttle feeler and carrying at its outer end a pivoted trip member that cooperates with the laterally proj ecting pin carriedby the heel of the feeler thread cutting mechanism whereby said cutting mechanism will be opened upon the return or forward movement ofthe shuttle feeler. l

A further obj ect is to provide a filling feeler knife tripper of the above mentioned character which will at all times be positive and efficient as well as automatic infits operation, the device being readily and easily attached tothe loom without necessitating any material alterations. Y l

A further object is to provide a device of the above mentioned character that' will tend to eliminate many broken bobbins and shuttles which results from the use of the type o knife trippers fnowin use. y y Furthermore a knife tripper of this'character will permit the shuttle to be set closer to the lay thus permittingthefilling knife to operate more efficiently. n

A still further object resides in the provision of alling feeler knife tripper which is simple in construction, inexpensive, strong and durable and further well adapted to the purposes for which it is designed. v 40 Other obfectsv and advantages Awill become apparent during thecour'se ofthe following description. Y

In thegaccompanying drawings,vforming a part of 'this'fspecicatiom and in which like numerals indicate likeparts throughout the same: y v

Figure 1 is a perspectiveview showing portions of a Vlling replenishing loom with my I improved tripping device associated therewith,` v

Figure 2 is a side elevation fof the supporting arm and the attaching bracket showing the pivoted trip in section, v

Figure 3 is a perspective view of the hori- Zontally disposed arm and the attaching bracket therefor, f v

Figure 4:, is a top plan Vview of the device per se,`

Figure 5 is a detail perspective View of the trip element per se, and f 'Figure 6 is a front elevation of a trip element showing the same mounted on the horizontally disposed arm, the latter being shown in'section.

In the drawings wherein for the purpose of illustration is shown the preferred embodiment of myrinvention, the numeral 1 designates a portion of the breast beam of a loom on which is adapted to be mounted the hopper stand not shown in they usual manner.

lThe shuttle feeler of the loom is shown at 2 and the same is pivotally supported at its lower end' on the stub shaft 3 in the manner also well'known in the art. The upper laterally disposed portion 4 of thev shuttle feeler has associated withthe outer end thereof the conventionalA cutting mechanism denoted generally by the reference character 5 Aand as the cutting mechanism is of the conventional construction, a disclosure thereof in the present instance is believed unnecessary.

The heel 6 that forms a part of the cutting mechanism carries the usual laterally projecting pin'7 which pin provides means for cooperation with a trippingV mechanism to open the 'cutter and the tripping mechanism that constitutes the present invention will be hereinafter described iny detail. s i

The shuttle feeler 2 is adapted for swinging movement transversely of the loom and o the usual guide bracket8 is provided force-` operation with the shuttle feeler in the man` ner also well known-in the art. Y

My improved filling feeler knife tripper is shown generally at 9 in the drawings and the samek comprises an 'angular attaching bracket that includes a rectangular shaped plate 10 for disposition across the top of the beam l, said plate being formed withfa central opening to accommodate the securing bolt 11, which bolt is also employed to fasten the hopper stand on the beam.

The opening through which the bolt l1 passes is indicated at 12. The forward end of the plate 10 is bent downwardly to form a flange 13 that engages with the front edge portion of the beam 1 in the lmanner as suggestedvery clearly in` Figures 1f-and'2. Y

Extending' outwardly from the depending flange 13 in a horizontal plane is the arm'14, the same being preferably-disposed adjacent the outer ,end of the pin 7. The outer end of the arm 14 is formedrwithlzthe spaced' openings 15.

The tripper 9 further incl-udesftheprovision of a trip Aelement lshown in detail in'Figurej an'dthis trip` element comprises a' body 17 that is formed with a longitudinal through slot 18 and extends from the forward to the rear of said' body. The upper inner corner portion of the body is cut away whereby to provide -a. relatively small yoke 19 at the upper forward corner of the body. Furthermore,V the slo-t 18 is of increasing length from the rear to the lforward edge of the body asis more clearly indicated in Figure 2 of the drawings, the' lower edgeof the slot at the rear 'edge portion of-thebody constituting a stop or shoulder QO'for-a purpose alsoto bepresently described.

The lower forward cornerv portion of the bodyis roundedtolform the cam face 21.

' The body 17 is formedwith registering openings inthe opposed sides oflthe slottedA portion thereof and the arm` `14 is disposed throughithe longitudinal slot 18an`d1a Cotter pin or :the: like shown atQQ extendsV through the registering openings formed in the sides of "the slotted portion of the body andv through either one of the openings lfformed inthe outer end portion ofthe arm 14 whereby to pivotally suspend the trip elementl on the outer` end of the horizontally Adisposed arm 14. f .The yoke 19 will engage the upper edge of the bar 14 to limit the rearward swinging movement of said trip element whileA the inclined bottom face`23 of the slot-22 will limit the forward swingingfmovement of the trip element. V

The trip element is suspended from'the. bar 14 so as tov be disposed in they pathof movement of the laterallyv projecting pin 7. The operation of my improved tripping device may be briefly stated as follows. As the shuttle feeler 2 moves rearwardly to anoperative shuttle feeling position, the :pin 7 :comes in contact withjthe camsurfacel of the trip element 17 Vand isthus forced downto open the thread cutterl 5, the `pin passing beneath the .lower corner of the trip.

As the shuttle feeler 2 returns toi its normal position, the pin 7 will strike the straight rear edge portion of the trip, 16; and will cause said trip'to swing, upwardly andlforwardly ure 2.

VThe Shoulder ,2e Win then abutwi'th the lower edge of the arm 14. The yoke 19 will Jlimitthe rearward swinging movement of thetripffwhen.thepin travels along the cam surface 21 of the trip as is obvious from the construction!illustrated.

It will thus be seen from the foregoing description; thatI'have provided a yielding trip for association withthe Cuttermehanism` for y positively -.and eflciently opening the cutter atl thev proper time, andlthsoperation being entirely. automatic.

A tripping Vdev-ice ofthe, above `.mentioned character can' be readilyandeasily installed on a loom without necessitatingaiiy material alterations ofl thelparts. of'theloomwith which the trippingdevice ist-ofbe associated Furthermore my improve'dtriipping,ldevice will; be strong and durable Vand@inegzpens-ive inl tsmanufacture. Vthle'` I have.
